Thursday’s meteor captivated many across the Southeast, but perhaps no one was quite as thrilled as the amateur meteorite chasers who track down bits of space rock and the astronomy researchers whose lifework is analyzing space activity.

Toshi Hirabayashi, a Georgia Tech associate professor who studies space operations, celestial mechanics, and planetary science, quickly began analyzing videos of the fireball Thursday “just for fun.”

Based on his rough calculations, the object was moving “definitely faster than 10 miles per second” or roughly 36,000 mph, he said.

While it’s fun to see smaller meteorites hit the Earth, it’s critical to prepare for when a larger meteor comes blazing in and does real damage. In 2013, a meteor the size of a house exploded 14 miles above Russia, Hirabayashi said.

“We are working so hard to monitor, as well as develop technologies to defend Earth,” he said.

Hirabayashi was also cited in articles published by FoxWeather and WSB TV.

Community engagement has illustrated notable educational applications of the Life Detection Knowledge Base (LDKB). The webtool's utility as an educational resource for next generation mission planners and astrobiologists was demonstrated when Georgia Institute of Technology astrobiology course instructor Jennifer Glass, associate professor in the School of Earth and Atmospheric Sciences, adopted it for a class project across several semesters from 2022 to 2023. In her graduate course, Seminal Papers in Astrobiology, Glass assigned students a biogenic or abiotic stance on a seminal astrobiology case study, such as the debate on the oldest microfossils. Students constructed and iterated arguments and evidence on their chosen topics for inclusion into multiple LDKB entries. A second example of the tool’s success in education came from a collaboration with the Young Scientists Program internship through the Blue Marble Space Institute of Science. Through both efforts, students developed arguments and supporting evidence for inclusion in the LDKB, gaining useful skills in peer reviewing, scientific writing, and scientific debate.

In an article published in Physics Magazine, School of Physics Ph.D. student Jingcheng Zhou and Assistant Professor Chunhui (Rita) Du review efforts to optimize diamond-based quantum sensing. According to Zhou and Du, the approach used in two recent studies broadens the potential applications of nitrogen-vacancy center sensors for probing quantum phenomena, enabling measurements of nonlocal properties (such as spatial and temporal correlations) that are relevant to condensed-matter physics and materials science.

On July 1, the Asteroid Terrestrial-impact Last Alert System (ATLAS) detected what was first believed to be an asteroid. As calculations for its orbit progressed, it was found to be from outside our solar system, only the third interstellar object ever detected.

[One] thing that astronomers discovered early on was that, rather than being an asteroid, the interstellar interloper dubbed 3I/ATLAS was a comet.

"It is doing things that we expect comets to do. It's producing the types of gasses that we see comets produce. It's got a coma and a tail now pointed in the expected direction," said James Wray, a professor at the Georgia Institute of Technology's School of Earth and Atmospheric Sciences. "I would say the short summary is it looks generally like a comet. But in detail, there are some intriguing differences from solar system comets."

A team of researchers from the School of Biological Sciences found some answers to the mystery of gene regulation by turning to the trusty roundworm C. elegans, a frequently studied model organism that has contributed to many important discoveries. In their new study published in GENETICS, the researchers used a powerful new approach to compare gene activity across several types of wildly diverse worm strains from all over the world to uncover their regulatory structure.

In this first of its kind study, the researchers crossed each strain of worm with their standard N2 lab strain to make a hybrid offspring. They then used a modern and powerful technique called allele-specific RNA sequencing to determine how the genes were being used in these new strains, and which parent DNA is driving the gene’s activity.
